Abstract

This utility model discloses a positioning structure for battery tab adhesive, comprising: a rotating base with two opposing columns fixedly connected to its upper end; a long plate and a mounting plate, both mounted on the columns; two positioning frames fixed to the upper surface of the long plate; a screw and a nut, both mounted on the mounting plate; and a pressure plate located at the lower end of the screw, contacting the inner wall of the positioning frames. By placing the battery tabs within a square frame and fixing them in place, and then using a falling pressure plate to limit the gap between the tabs and the pressure plate, the maximum thickness of the tab adhesive is limited. The use of a threaded mechanism to change the falling height increases the accuracy of controlling the gap between the pressure plate and the tabs.

Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a positioning structure for battery tab adhesive. Background Technology

[0002] The assembly of tabs and tab adhesive often employs manual positioning or simple tooling. Operators rely on experience to attach the tab adhesive to the pre-set position on the tab, and then fix it by manual pressing or simple clamps. This method not only depends on the operator's skill level, but also suffers from poor positioning consistency, making it prone to tab adhesive misalignment and skew. Furthermore, common battery tabs are flexible, so they are easily deformed under pressure during the addition of tab adhesive, affecting the quality of the finished battery. In addition, traditional positioning mechanisms lack measures to limit the thickness of the tab adhesive. If the thickness of the tab adhesive is uneven during the bonding process, the tooling must be disassembled and readjusted, seriously affecting the efficiency of battery processing. Summary of the Invention

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a positioning structure for battery tab adhesive, which facilitates quick fixation of battery tabs, improves the convenience and accuracy of controlling the thickness of tab adhesive, and has a simple structure that is easy to use and maintain.

[0004] This utility model also provides a positioning structure for a battery tab adhesive as described above, comprising: a rotating base with two opposing columns fixedly connected to its upper end; a long plate and a mounting plate, both mounted on the columns; two positioning frames, both fixed to the upper surface of the long plate; a screw and a nut, both mounted on the mounting plate; and a pressure plate, located at the lower end of the screw and in contact with the inner wall of the positioning frames. This facilitates quick and easy fixing of the tabs and improves the ease of limiting the maximum thickness of the tab adhesive.

[0005] According to the positioning structure of the battery tab adhesive described in this utility model, bolts are provided on both the left and right sides of the long plate and the mounting plate, and multiple bolts respectively penetrate the long plate and the mounting plate and contact the column. This improves the stability of the long plate and the mounting plate.

[0006] According to the positioning structure of the battery tab adhesive described in this utility model, the positioning frame is made of transparent material, and the front surface of the positioning frame is fixedly connected with scale lines. This improves the convenience of judging the height of the pressure plate.

[0007] According to the positioning structure of the battery tab adhesive described in this utility model, a load-bearing plate is provided at the rear end of the long plate, and protrusions and slots are respectively provided on the side of the load-bearing plate opposite to the long plate. This increases the stability of the battery after placement.

[0008] According to the positioning structure of the battery tab adhesive described in this utility model, both the surface of the protrusion and the inner wall of the slot are provided with a magnetic coating, and the protrusion is in contact with the inner wall of the slot. This increases the stability when the load-bearing plate is in operation.

[0009] According to the positioning structure of the battery tab adhesive described in this utility model, the rotating base is provided with a storage cavity. When the positioning structure is not used, the load-bearing plate is located inside the storage cavity, which facilitates the storage of the load-bearing plate.

[0010] According to the positioning structure of the battery tab adhesive described in this utility model, the rotating base consists of a rectangular base plate and a disc, with the disc rotatably connected to the bottom of the rectangle, and the storage cavity located on the rectangular base plate. This improves the convenience of maintaining the rotating base.

[0011] According to the positioning structure of the battery tab adhesive described in this utility model, the nut is fixedly connected to the upper surface of the mounting plate, and the lower end of the screw passes through the mounting plate and is rotatably connected to the pressure plate. This improves the convenience of using the screw. Beneficial effects

[0012] The positioning structure of the battery tab adhesive in this technical solution uses a positioning frame to fix the battery tabs, while a falling pressure plate limits the space above the tabs to control the total thickness of the tab adhesive on the tab surface. The screw controls the falling of the pressure plate, which improves the accuracy of controlling the space above the tabs and ensures the consistency of the tab adhesive thickness during batch processing of battery tabs. The battery tab fixing component that can slide up and down and the easily disassembled load-bearing plate make it convenient for users to assemble batteries of different thicknesses but the same tab size.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figure 1-4 This utility model provides a positioning structure for battery tab adhesive, comprising: a rotating base 1, with two opposing columns 2 fixedly connected to the upper end of the rotating base 1; a long plate 3 and a mounting plate 6, both of which are mounted on the columns 2; two positioning frames 5, both fixed to the upper surface of the long plate 3; a screw 7 and a nut 8, both of which are mounted on the mounting plate 6, with the nut 8 fixedly connected to the upper surface of the mounting plate 6, and the lower end of the screw 7 passing through the mounting plate 6 and rotatably connected to a pressure plate 9; and a pressure plate 9, located at the lower end of the screw 7 and in contact with the inner wall of the positioning frames 5.

[0017] Bolts 4 are provided on both the left and right sides of the long plate 3 and the mounting plate 6. Multiple bolts 4 pass through the long plate 3 and the mounting plate 6 respectively and contact the column 2. The bolts 4 use the threaded self-locking structure to squeeze the column 2, increasing the friction force on the long plate 3 and the mounting plate 6, and improving the stability of the long plate 3 and the mounting plate 6 when they are in action.

[0018] The positioning frame 5 is made of transparent material, and the front surface of the positioning frame 5 is fixedly connected with the scale line 10. The material of the positioning frame 5 matches the scale line 10, which makes it convenient for staff to position the height of the pressure plate 9 in real time.

[0019] The rear end of the long plate 3 is provided with a load-bearing plate 11. The side of the load-bearing plate 11 opposite to the long plate 3 is provided with a protrusion 13 and a slot 14 respectively. The load-bearing plate 11 is used to support the battery and increase the stability of the electrode tabs entering the positioning frame 5.

[0020] Both the surface of the protrusion 13 and the inner wall of the slot 14 are provided with a magnetic coating. The protrusion 13 contacts the inner wall of the slot 14, and the protrusion 13 with magnetic adsorption capability cooperates with the slot 14 to increase the stability of the load-bearing plate 11 after it is engaged with the long plate 3, and improve the load-bearing capacity of the load-bearing plate 11.

[0021] The rotating base 1 is provided with a storage cavity 12. When the positioning structure is not in use, the load-bearing plate 11 is located inside the storage cavity 12. The storage cavity 12 is used to store unused load-bearing plates 11 to prevent the load-bearing plates 11 from being lost due to careless placement.

[0022] The rotating base 1 consists of a rectangular base plate and a disc. The disc is rotatably connected to the bottom of the rectangle, and the storage cavity 12 is located on the rectangular base plate. The rotating base 1 utilizes its own rotating structure to improve the convenience of the staff using the scale line 10.

[0023] Working principle: When placing a battery, first rotate the side of the slot 14 to face the operator (normally, the side of the storage cavity 12 faces the operator). Then, take out the load-bearing plate 11 and insert the protrusion 13 into the slot 14. The battery can then be placed on the surface of the load-bearing plate 11. At the same time, add the battery tabs to the positioning frame 5 from front to back in a socketing manner, or slide the mounting plate 6 up to move the mounting plate 6 away from the long plate 3. Then, press the tabs into the positioning frame 5 from top to bottom. Then, slide the mounting plate 6 down until the pressure plate 9 enters the positioning frame 5. At this time, rotate the bolt 4 to increase the friction on the mounting plate 6, thereby fixing the mounting plate 6. Then, rotate the scale line 10 to face the operator, and then rotate the screw 7 downward. The pressure plate 9 is driven by the screw 7 to slide down inside the positioning frame 5, thereby changing the distance between the tabs and the pressure plate 9. Stop rotating the screw 7 after the scale line 10 is below the lower surface of the pressure plate 9. This is to inject tab glue into the gap at the rear end, so that the tab glue fills the gap between the pressure plate 9 and the tabs.

[0024] By using the pressure plate 9 to restrict the space for the tab adhesive filling, the tab will not be subjected to additional pressure when the tab adhesive is added later. Therefore, the tab will not be subject to any risk of deformation during the tab adhesive addition process, and there will be no additional pressure. Thus, there will be no situation where the tab adhesive seeps into the gap between the tab and the positioning frame 5. After the tab adhesive is fixed, there will be no excess parts on the edge of the tab. Since the pressure plate 9 restricts the space for adding tab adhesive, a flat liquid outlet head is required to assist in evenly filling the gap between the pressure plate 9 and the tab with tab adhesive.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
